Loggerhead Sea Turtle Facts, Pictures & Information For Kids & Adults
Apr 11, · Predators also rely on loggerhead hatchlings for food, while more than a hundred species of animals—including barnacles, crabs, and algae—live on their shells. Ghost crabs cause harm to many baby loggerheads. Most of the predation on sea turtles takes place at the beginning of their lives when they are eggs, hatchlings, or juveniles. Once they mature, their large size and hard shells protect them from most of their natural predators.
Loggerhead sea turtle facts, pictures and information for kids and adults. The loggerhead sea turtle is the second-largest of the seven species of sea turtle. Read on to get the lowdown on this threatened ocean voyager …. The loggerhead sea how to clean system registry is a marine reptile. It is the largest hard-shelled turtle and the second largest turtle in the world after the leatherback sea turtle Dermochelys coriacea.
The leatherback turtle has got a soft shell. The global loggerhead sea turtle population is divided into 10 subpopulations, all of which differ in their genetic makeup and physical characteristics.
The carapace the shell covering the back of the turtle is typically reddish brown in color, while the plastron the shell covering the underside of the turtle tends to be pale yellow. The rest of the body ranges in color from yellowish orange to brown. The color of the hatchlings is usually reddish to dark brown. The loggerhead sea turtle inhabits saltwater and estuarine habitats, including the open ocean and shallow coastal waters. Hatchlings inhabit mats of Sargassum algae that float in warm ocean currents.
Juveniles are found in coastal waters more often than non-nesting adults. Only nesting females come ashore to nest on sandy beaches; once male hatchlings enter the sea, they never again return to the land. Like all reptiles, the loggerhead sea turtle is ectothermic cold-blooded. This means that it has no physical means to alter its body temperature other than simply swimming to a different area i. When this occurs the turtle can barely swim, and floats near the surface where it is vulnerable to boat strikes or to becoming beached on the shore.
To avoid cold stunning, loggerheads resident in temperate waters migrate to tropical and subtropical waters during the winter months. Adult loggerheads also migrate between feeding grounds and nesting areas. The turtles use magnetic navigation to return to the same nesting area again and again.
The loggerhead sea turtle is usually active during the daylight hours. Longer dives can last up to 7 hours. Aggression between individuals is common. Females fight over access to good feeding grounds; males attack each other during the mating season. Conflicts begin with threat displays.
Loggerhead sea turtles will have reached sexual maturity by the time their carapace exceeds 90 cm 35 in in length. This usually occurs between 17 and 33 years of age. The breeding season takes place over 6 weeks in the early summer. The male loggerheads may nuzzle, bite and gesture to the females with head and flipper movements during courtship. Typically, a female will nest 2 to 5 times during one breeding season.
She will then produce no what can birth control do to you for the next 2 or 3 years. The eggs incubate in how to take snapshot of a web page chamber excavated by the female for 45 to 80 days. The how to break a plateau on weight loss of the hatchlings is determined by the temperature in the nest.
Temperatures in-between these produce a mix of male and female hatchlings. Newly-hatched young are about 4. The loggerhead sea turtle is an omnivore i.
It preys on a wide range of animals, and also eats algae. The bulk of its diet is made up of various bottom-dwelling invertebrates. These include bivalves and gastropods, which the loggerhead crushes with its strong jaws. Young loggerhead sea turtles are vulnerable to numerous predators both on land and in the sea. Eggs and new hatchlings are hunted by crabs, snakes, rats and seabirds among many others. In the ocean, various fish species and crabs prey on young loggerheads.
Their large size, shell and tough scales protect adult loggerheads from most predators. However, they are still vulnerable to big sharks, seals and killer whales.
The rating is given to the global population; the status of individual subpopulations varies greatly. Other dangers faced by the loggerhead sea turtle include pollution, marine debris, pathogens and climate change.

Meet The Loggerhead Sea Turtle: Introduction
Sep 01, · The loggerhead turtle is a large-bodied sea turtle named for its broad, strong head. These turtles are generalists predators and use their muscular heads and powerful jaws to crush the shells of queen conch, Caribbean spiny lobsters and other hard-shelled invertebrates. Feb 25, · There are some predators of sea turtles as adults, but these marine reptiles are most vulnerable when in the egg and as hatchlings (small turtles recently emerged from the egg). Predators of eggs and hatchlings include dogs, cats, raccoons, boars, and ghost crabs. Feb 10, · Young loggerhead sea turtles are vulnerable to numerous predators both on land and in the sea. Eggs and new hatchlings are hunted by crabs, snakes, rats and seabirds among many others. In the ocean, various fish species and crabs prey on young loggerheads. Their large size, shell and tough scales protect adult loggerheads from most predators.
The largest of all hard-shelled turtles, loggerheads are named for their massive heads and strong jaws leatherbacks are bigger but have soft shells. Their reddish-brown shell, or carapace, is heart-shaped. Their front flippers propel them through the water like wings, and their hind feet stabilize and steer them. While adults males generally weigh about pounds , loggerheads of more than a thousand pounds have been found.
These turtles feed on invertebrates, whose shells pass through their digestive systems and, upon excretion, fall back to the bottom of the ocean for other animals to eat as a calcium source. Predators also rely on loggerhead hatchlings for food, while more than a hundred species of animals—including barnacles, crabs, and algae—live on their shells. They prefer coastal habitats in temperate and subtropical regions, though they often frequent inland water bodies and will travel hundreds of miles to reach them.
Mature loggerhead females often return to the beach where they hatched to lay their own eggs, sometimes traveling thousands of miles. Each stretch of coastline has its own magnetic signature, and these turtles remember and use them as guides.
Breeding occurs year-round but peaks in the summer months. Females may lay two to five clutches of up to eggs in a season with different mates. Loggerhead sea turtles are primarily carnivores, and their strong jaws allow them to crush conchs, bivalves , and horseshoe crabs. They also eat jellyfish, shrimp, sponges, fish, and sometimes even seaweed and sargassum.
Loggerheads are the most common of all the sea turtle species in waters the waters of the United States. But persistent population declines due to pollution, shrimp trawling, and development in their nesting areas, among other factors, have kept this wide-ranging seagoer listed as threatened under the U.
Endangered Species Act since Fisheries pose the greatest threat to the loggerhead turtle, which often gets caught accidentally in fishing gear like trawls and nets.
Humans also have killed these turtles for their meat and skin for years, while ocean debris can injure or kill them. Climate change is also throwing off the ratio of male and female sea turtles.
The temperature of the sand in which turtles are hatched determines their sex—and, as those temperatures rise, more female loggerheads are being born. There are efforts underway around the world to save the loggerhead sea turtle. In the southeastern U.
Some communities have developed ordinances reducing the amount of artificial light allowed near nesting sites as it can disorient hatchlings making their way from the nest to the sea. Since , the U. When these devices are fitted into the neck of a trawl net, larger animals like turtles bounce off their grid-like bars while smaller animals like shrimp pass through. In spite of these protections, loggerhead sea turtle populations continue to decrease.
Given the migratory nature of these animals, researchers say that long-term international cooperation is essential to their stability. All rights reserved. Animals Photo Ark. Loggerhead sea turtle.
